IMPROVEMENT IN SPRING- BEDS.

My invention has for its object to improve the construction of springbeds, which shall be at the same time portable, cheap, durable, and notliable to get out of repair; and to this end,

The invention consists in so constructing the bed that itcan be folded,onejrartor one half upon the other, and when .so foldcih'i can be easilyboxed fortransportation, oritcan be upholstered, and placed againsttheside of a room, to be used asa seat, each folding part being providedwith springs, secured in place and arranged as will be hereinafterdescribed.

. In the drawing'-- A is the top of the bed, niade of a series oflongitndinal strips, each strip forming the bearing for a set ofsprings. This top is jointed and hinged in the middle, so that it canbefolded' up, as shown in fig. 2. The strips of the top are covered withcanvas,

or other suitableauaterial, to keep the same level,

and make a plane surface to put the iuatress upon.

B B. are the bottom rails, which rest upon the bedstcad or floor. Theseare connectedtogether by wide strips of wood D, upon which the springsare fastcued.

0 Care the springs, placed between and fastened to the top strips andbottom strips 1), by bolts or screws 1*.

These bolts or screws h are inserted through the top strips and bottompiece D, and a strip of metal, or a metal plate, E, is placed betweenthe two extreme coils on each end of the springs, and through which thescrews or bolts F are passed, and a nut, G, placed upon them, to keepthe same steady and firm.

By this metal strip being passed between the coils at the extreme endsof the springs, and fastened by the screws, the-top can only be raisedto a'certain distance. 7 v i The top A and bottom rails B B are alsoconnected and" kept together by diagonal strips of webbing, or othersuitable material. These strips also prevent longitudinal displacementof the springs.

The advantage to be derived from my mode of construction is, that whenthe device is unfolded, as shown by dotted lines in fig. 2,- the bed isready,

whether it be placed on the floor or a bedstead, to receive themattress.

When folded, it can be upholsteled and used as a seat. It also, in thiscondition, forms a "compact package for transportation, easilyhandled,,and not liable to be broken or disarranged while being moved,and by my mode of fastening the springs to their seats with the metalplate, and bolts, and nuts, they cannot be displaced by any ordinaryusage, but are always kept in the proper place and position, thusrendering the device simple and economical.

Having thus described my invention,

What I claim as new therein, and desire to secure I by Letters Patent,is

The spring bed-bottom, consisting of the two fold-
